Abstract
To manufacture a honeycomb body, it is proposed that at least one stack is layered up from a plurality of at least partly structured sheet metal layers. Each stack is folded over about a bending line such that a sheet metal pack is formed having a curved first end area and a second end area. The second end area has a first end section and a second end section. A first end face of the first end section forms a first angle with a central plane, and a second end face of the second end section forms a second angle with the central plane, wherein the first angle is smaller than the second angle. The sheet metal packs are held by looping devices disposed in a mold, and the sheet metal pack is looped into a honeycomb body by rotation of the looping devices.
